Which of the following expressions correctly uses the properties of summations to represent
madam [21]

Answer:

Option C is correct.

7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

Step-by-step explanation:

Given the expression:  \sum_{i=1}^{18} (7i^2+9)

Using properties of summation:

  • \sum_{i=1}^{n} (a+bi) =\sum_{i=1}^{n} a + \sum_{i=1}^{n} bi
  • \sum_{i=1}^{n} a = an

Using properties of summation in the given expression we have;

\sum_{i=1}^{18} (7i^2+9)

= \sum_{i=1}^{18} 7i^2 + \sum_{i=1}^{18} 9

=7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

Therefore, the following given expression uses the properties of summation to represents is, 7 \cdot \sum_{i=1}^{18} i^2 + 9 \cdot 18

The slope of the line below is -5 which of the following is the point-slope form of the line (2,-8)
insens350 [35]
The point slope form has the following syntax.

y - y_1 = m(x - x_1)
m = slope = -5 
y - y_1 = -5(x - x_1)
(x,y) = (2,-8)
x_1 = 2
y_1 = -8
y - y_1 = -5(x - x_1)
y - (-8) = -5(x - 2)
y + 8 = -5(x - 2)  <------Answer
